- an interconnection equipment 1 between at least one service platform and at least one user terminal 2 k for conveying a service flow between a service interface ISj (j ⁇ 1, ..., n) of said service interface interconnection equipment 1 and a terminal interface Ii (i ⁇ 1 m) of said interconnection equipment 1, in which the invention is implemented is described with reference to FIG. 1.
- the service platform not shown on FIG. the figure, is located remotely in the network of a telecommunications operator wishing to make service flows available.
- the interconnection equipment 1 as represented in FIG. 1 comprises, within it, a first series of interfaces called terminal interfaces h to 1 m , at least one data frame analysis module 10, at least a control module 11, at least one routing module 12 and a second series of ISi interfaces to IS n , called service interfaces.
- a user terminal 2k connected to the interconnection device 1 by means of a terminal interface Ii (i G 1, ..., m)
- 2 k sends requests user terminal is in the form data frames to service platforms to retrieve service flows.
- These frames contain fields whose values indicate which type of service flow Ie user terminal 2 k is able to receive, for example from one of the following services: • videophone, internet, digital television, etc.
- the terminal interfaces I 1 to 1 m to which are connected the different user terminals 2 k are, for example, USB ports, Ethernet ports, WlFI ports, or Bluetooth ports.
- a terminal interface h to l m can be connected to a plurality of user terminals 2 k .
- the terminal interface 12 is connected to two user terminals 21 and 22. According to the invention, the different terminals connected to said terminal interface all require the same service flow to be received.
- the data frames transmitted by the different user terminals 2 k are intercepted at the output of the terminal interfaces I 1 to Im by at least one frame analysis module 10.
- This module has the function of extracting the values of certain fields contained in some of these frames. These fields indicate, among other things, as has been said above about the nature of the service flow requested by each user terminal 2 k connected, as well as the user terminal itself by providing information such as its physical address, such as a MAC address, @ MAC2 k .
- the data frames are sent in the network to the service platforms.
- the information resulting from the analysis of the data frames is stored in at least one first persistence file of the interconnection equipment 1, referred to as the "Terminals" file.
- the service flows requested by the user terminals 2k connected to an interconnection equipment 1 arrive in the interconnection equipment 1 by a modem for example (not shown in the figures). Hs are then distributed to different service interfaces ISj (] 6 1, ..., n) of said modem, These ISj service interfaces are access interfaces dedicated, each, to a particular service flow. Each of them is identified for example by his physical address, @MAC
- the control module 11 located at the output of the frame analysis module 10, receives the information concerning the user terminals 2 k collected by said frame analysis module 10.
- the control module 11 also receives information concerning the physical addresses of the terminal interfaces Ij to which the terminals 2 k are respectively connected.
- the control module 11 knows by querying the persistence file "Service Interfaces", the distribution of the different service flows on the service interfaces ISi to IS n as well as the physical addresses of the said service interfaces ISi to IS n . Using all this information, the control module 11 then sends instructions to the routing module 12.
- the routing module 12 creates links between the service interfaces ISi to IS n and the interfaces of Termina! h to l m corresponding to ensure the routing of the service flow to user terminals 2 k concerned.
- the creation of links between the service interfaces ISj and the terminal interfaces I consists of setting up a routing or bridging between said service interfaces IS j and ies said terminal interfaces Ii.
- FIG. 1 shows a first particular embodiment of the invention.
- the routing module 12 comprises at least one router 12a and at least one bridge 12b.
- user terminals 2 ⁇ able to receive routing routed service flows and bridged service routes can be connected to a single interconnection equipment 1.
- the routing module 12 comprises only a router or a bridge.
- FIG. 3 shows a third particular embodiment of the present invention.
- the interconnection equipment 1 comprises several frame analysis modules 10p.
- Each of these frame analysis modules 1Op intercepts data frames from one or more terminal interfaces I,. This embodiment provides faster processing of the data frames. This embodiment can be combined with the embodiments of the present invention described above.
- FIG. 4 represents the nesting of the various logical modules constituting a frame analysis module 10 p .
- These logical modules are three in number; a first logic module SP1 realizing j 'of initia ⁇ satiofi the interconnection equipment 1, a second logic module SP2 ensuring the detection and identification of any new user terminal 2 k connected to the interconnection equipment 1 and a third logic module SP3 ensuring the recovery of information necessary for the routing the service flows to the corresponding terminal interfaces h to l m .
- FIG. 5 represents the different constituent steps of the initialization logic module SP1 of the frame analysis module 10 p .
- a first step E10 the interconnection equipment starts. It is then a question of testing, during the step E11, whether it is the first start of the interconnection equipment 1.
- the logic module SP1 executes the step E12.
- a service called default service is assigned to all terminal interfaces Ij (i ⁇ 1, ..., m).
- the default service is usually the internet service, maize can be any other service.
- step E 13 identification information of a terminal interface h (i ⁇ 1, ..., m), for example the physical address (Q) MAC U of the terminal interface Ij 1 and identification information of a default service are stored in a third file of persistence of the interconnection equipment 1 said file "Terminal Interfaces".
- a default service is an advantageous choice of impregnation since, i! allows to offer said default service to a terminal that is not intended to send frames to identify a specific service required by this terminal.
- Personal computers are the most common example of terminals that are not intended to send frames to identify the service they require.
- the service most often required by a personal computer is "Internet", so it is advantageous to choose
- This step consists in transmitting, for each terminal interface I 1 , to the control module 11, the identification information of the service required by the terminal and the terminal interface Ij.
- FIG. 6 represents the different constituent steps of the logical module SP2 for detecting and identifying terminals 2k connected to the interconnection equipment 1 by means of the interfaces to terminals Ii (ie 1 m).
- the data frame analysis module 10 receives, from one of the terminals 2 k connected to the interconnection equipment 1, a data frame to be analyzed. He then executes steps E20 and E21. In a first step E20, the data frame analysis module extracts the physical address @MAC 2k from the terminal 2 k from which the analyzed data frame originates. During this same step, the data frame analysis module 10 receives from the operating system of the interconnection equipment 1 the identifier of the terminal interface Ij by which the frame of data to analyze is received.
- step E21 the value of the physical address @ MAC2k of the terminal 2 k contained in the received data frame is searched for in the "Terminals" persistence file.
- the value of the physical address of said terminal 2 ⁇ is present in the persistence file "
- step E22 is recovered in the persistence file "Terminals" the service identification information stored in association with the physical address of @ MAC 2k 2k finished it.
- the method executes step E30.
- the frame analysis module 10 In order to save computing time on the processor of the interconnection equipment 1, the frame analysis module 10 only intercepts certain particular data frames. The choice of the frames of data to be intercepted is the result of the knowledge of the different types of frames, for example ARP (acronym for the English acronym Address Resolution Protocol), DHCP (of the English acronym Dynamic Hosî Configuration Protocol) , data that can be transmitted by the various terminals connected to the interconnection equipment 1.
- the data frames to be intercepted by the frame analysis module 10 are frames sent infrequently by the terminals 2 k and some of which fields contain the information necessary to perform the method of analyzing the data frames according to the invention.
- step E30 the analysis module tests the nature of the data frame intercepted by the data frame analysis module 10. If the intercepted data frame is a particular frame within the meaning of the invention , then step E31 will be executed. If the intercepted frame is not a particular frame in the sense of the invention, the detected terminal 2 k is associated, in the persistence file "Terminals", with the default service, which corresponds to the step E34, In In a particular embodiment of the present invention, the default service is a service whose stream is routed by routing. Nevertheless, the default service may be a service whose stream is routed by means of a bridge. The choice of the routing type of the default service flow is the responsibility of the telecommunications operator.
- step E31 the particular fields of the intercepted data frame are read to retrieve the information they contain.
- This information is, among others, the name of the service, the serial number of the connected terminal, the name of its manufacturer, the software version supported by the terminal.
- Step E32 consists of testing the nature of the service flow requested by said terminal, that is to say, to determine whether it is a service whose flow is routed or of a service of which the flow is conveyed by a bridge.
- step E33 the name of the new service, as well as its nature, is stored in the persistence file "Terminal Interfaces" instead of the name of the old service which is the default service.
- the frames intercepted by the frame analysis module 10, in the step E30 are DHCP frames. These frames are frames rarely sent by terminals such as video telephony terminals or digital television tuners. In these frames, at least one of the fields 60 and 77 contains all the information necessary for the execution of the method according to the invention.
- FIG. 7 represents the various steps constituting the logical module SP3 for detecting the information necessary for routing the service flows to the corresponding terminal interfaces h to l m .
- step E40 the service requested by the terminal 2 k whose frames have been analyzed is compared with the service stored in the persistence file "Interfaces". If the services are different, the method executes the step E41 In a step E41, the service requested by the terminal 2 k is stored in the persistence file "Interfaces" in place of the previously stored service.
- the frame analysis module 10 transmits to the control module 11 the identification information of the required service and the terminal interface Ij whose frames have just been analyzed. remember that the control module 11 knows the identifier of the service interface associated with each service. Depending on the service requested, the control module 11 carries out the routing by implementation of routing or bridging.
- the method according to the invention thus makes it possible to automatically configure the interfaces of an interconnection equipment. However, this method also makes it possible, by using other information contained in particular fields of the scanned data frames, to offer other functionalities.
- the data frame analysis module 10 makes it possible by comparing the name of the manufacturer of a terminal resulting from the analysis of a data frame with the names of manufacturers stored in a persistence file called "Authorized Terminals" accept or deny the connection of the terminal to Interconnection Equipment 1.
